Abstract

This study investigated actor and partner effects involving middle-aged husbands' and wives' stressful work conditions (SWCs), positive affect (PA), and health outcomes in a dyadic trajectory context in three steps. First, examination of husbands' and wives' individual trajectories showed significant interindividual variations in SWCs and PA over time. Second, a dyadic growth curve model incorporating both husbands' and wives' growth curves of SWCs and PA showed that husbands' and wives' trajectories of SWCs over their early middle years (1991-1994) were negatively associated with their own parallel trajectories of PA independent of depressive symptoms trajectories. Finally, most of the growth factors of PA trajectories of husbands and wives (1991-1994) predicted their own residual changes in physical illness and overall physical health in 2001. In dyadic models, although contemporaneous correlations between most of the study constructs between husbands and wives were significant, all partner effects involving growth parameters of SWCs, PA, and health outcomes were not significant. Most of the indirect effects from SWCs growth factors to health outcomes through PA were significant. The findings suggested that PA was an important health resource for middle-aged husbands and wives that mediates the influence of one's SWCs on own physical health outcomes.
